[0035] Performance

Embodiment 1

[0036] Comparing Example 1 with Comparative Example 1, it can be seen that the addition of PA6 can improve the impact strength of the material. Comparing Example 2 with Comparative Example 1, it can be seen that the addition of PPS can improve the thermal deformation, tensile and bending strength of the material. Comparing Example 3 with Example 2, it can be seen that with the increase of PPS, the tensile bending of the material increases, and the impact strength decreases. Comparing Example 4 with Comparative Example 1, it can be seen that the addition of VTECNSF600 can increase the flow rate of the material, the mechanical properties will decrease, and the thermal properties will not be affected. Optimum formula of the present invention is embodiment 2.

Abstract

The invention provides a high-performance modified polyamide composite material. The high-performance modified polyamide composite material comprises, by weight, 8-12% of nylon 6, 30% of glass fibers, 10-20% of polyphenylene sulfide, 0.5-4% of a filler, 1-5% of a compatilizer, 0.1-0.5% of a processing auxiliary agent and the balance nylon 66. The invention also provides a preparation method of the high-performance modified polyamide composite material. The high-performance modified polyamide composite material can be used for machinery, apparatuses and instruments, automobile parts, electrical and electronic products, railway, household electrical appliance, communication, spinners, physical culture leisure articles, oil pipes, fuel tanks and precision engineering products.

Description

technical field [0001] The invention belongs to the field of materials science, and relates to a polyamide resin material, in particular to a high-performance modified polyamide composite material and a preparation method thereof. Background technique [0002] Polyamide resin, the English name is polyamide, referred to as PA. Commonly known as nylon (Nylon), it is a general term for polymers containing amide groups in the repeating unit of the main chain of the macromolecule. Polyamide has high tensile strength; excellent toughness and impact resistance; good self-lubrication, abrasion resistance and chemical resistance; good low temperature characteristics; self-extinguishing. Due to the many characteristics of nylon PA plastic raw materials, it is widely used in machinery, instrumentation, auto parts, electronic appliances, railways, home appliances, communications, textile machinery, sports and leisure products, oil pipes, fuel tanks and some precision engineering produc...
